Versuchsvorschrift

The procedure described in Example 1 was repeated, except that dihydropyran (1.37 ml) and methyl 4-aminobutanate hydrochloride (1.69 g) were successively reacted with (RS)-2-(4-chlorobenzenesulfonylamino)-3-hydroxypropanoic acid (2.80 g) to obtain (RS)-2-(4-chlorobenzenesulfonylamino)-N-(3-methoxycarbonylpropyl)-3-(tetrahydropyran-2-yloxy)propanamide (3.12 g).
